Evoqua water treatment system LaboStar RO DI
Thanks to its energy-efficient low-energy membranes, this system offers high-purity water quality with minimal energy consumption, especially in laboratory environments. Comparisons such as the [Evoqua UltraClear 12 RO UV] show that devices of this type impress with their integrated module solutions and reliable disinfection concepts. The model described here also impresses with its compact design with integrated storage tank and a flexible removal concept that is suitable for different requirements in laboratory operation.
Performance features and design
During development, great attention was paid to low-noise operation and ease of use. In particular, the existing dispenser concept offers a dispensing option directly at the point of use or via a rear outlet for a pressure-supported supply. The key aspects also include:
- Integrated 7-liter storage tank for continuous pure water availability
- Conductivity monitoring of all important process steps (RO and DI water)
- Choice between charged or uncharged 0.2 µm sterile filters
- Maintenance-friendly quick couplings for filter modules
- Practical disinfection routine for quick and easy reprocessing
- Dispensing capacity of up to 1.2 l/min at the dispenser
- Retention rate for salt and particles of over 98 %
The final DI cartridge is essential for producing type II reverse osmosis water with a conductivity of less than 0.1 µS/cm. This ensures that even particularly sensitive applications - such as in molecular biology or analytics - receive pure water that is free from inorganic impurities, particles and microorganisms. Thanks to its variability, the device is suitable for laboratories with medium water requirements that also attach great importance to providing safe and standard-compliant ultrapure water.
Technical data at a glance
- Permeate output: 10 to 13 l/h depending on the water temperature
- Salt retention rate: 98-99 % in the RO process
- Pure water quality: Below 0.1 µS/cm after DI stage
- Particle separation: Over 99 % > 0.2 µm
- Bacteria retention: At least 99 %
- Feed water requirement: 14-20 l/h at an inlet pressure of 0.1-5 bar
- Maximum working pressure: 6 bar
In addition, the integrated 7-liter tank can be optionally expanded with 30- or 60-liter tanks to provide flexibility when more pure water is required. With an output of up to 184 W and power connections of 100-240 V/50-60 Hz, the system also adapts to different laboratory environments. To comply with common laboratory standards, it fulfills typical industry requirements to ensure safety and quality.
Application examples
- Precise analyses in chemical research: the high water quality reduces interference factors and possible contamination during sample preparation.
- Molecular biology work: Sterile ultrapure water conditions are essential here, for example for DNA and RNA molecular analyses.
- General laboratory routine: Whether rinsing sensitive glassware, producing buffer solutions or supplying autoclaves - the device reliably supplies high-quality water.
- Pharmaceuticals and drug development: pure water for analytical processes or media production where low conductivity is particularly important
Frequently asked questions (FAQs)
How often do filter modules need to be changed?
The filter modules are changed regularly depending on the raw water quality and intensity of use. The integrated maintenance message indicates in good time when a replacement is due.
Can the appliance be connected to a larger external storage tank?
Yes, the standard capacity of 7 liters can easily be expanded with a 30 or 60 liter tank.
Is the system easy to disinfect?
The quick-release couplings and practical disinfection process make cleaning quick and easy.
What certifications are available
The device is designed for typical responsibilities in laboratory and research facilities and meets the requirements of common standards, for example in terms of electrical safety and microbiological purity (when using a 0.2 µm sterile filter).
Which substances can affect the water quality?
Elevated salt and particle concentrations, residual chlorine or iron in the feed water can reduce the membrane performance. The system is designed to effectively reduce or remove these substances.
Conclusion
With its compact, low-noise design and flexibly adjustable treatment capacity, this system is a reliable piece of laboratory equipment that is suitable for a wide range of cleaning and analysis tasks. It enables constant pure water quality in the range below 0.1 µS/cm, reduces operating costs thanks to energy-optimized membranes and offers convenient operation and fast maintenance thanks to intelligent disinfection methods. This ensures a high standard of ultrapure water supply in the long term, even in demanding laboratory environments.
